Maybe, but there's nothing in this article or the referenced Vice News article to support this claim.
Click bait BS.
Here’s the story; looks like they cited Comey’s report.
Comey said it was top secret material that was sent out.
The Hillary email scandal keeps getting uglier: 3 key aides got messages clearly marked ‘Top Secret’
July 23, 2016 | Carmine Sabia |
Emails marked “top secret” were sent from Hillary Clinton’s private server to the email addresses of three of her top aides.
They included 22 such emails in seven email chains sent to Jacob Sullivan, Cheryl Mills, and William Burns, according to State Department documents obtained by Vice News on Friday.
The 22 emails were originally held back from emails received by Vice News in response to a 2015 Freedom of Information Act request it made because releasing them to the public would have caused “exceptionally grave damage” to national security.
“Seven e-mail chains concern matters that were classified at the Top Secret/Special Access Program level when they were sent and received,” FBI Director James Comey said in his report. “These chains involved Secretary Clinton both sending e-mails about those matters and receiving e-mails from others about the same matters.”
The emails were not put under a higher level of classification after the fact, according to Comey’s report.
